This module is divided into two sections the declarations for this module
(i.e. the function signatures) are listed in 'fxid.h'.  The definitions
(i.e. the actual code and variables) are listed in 'fxid1.c' and 'fxid2.c'.
The appropriate piece of code you need for your application should be
included in your top level program file.
